Drivers are libraries that provide an interface to an external service provider. The libtcl.cfg file provides a template into which you enter all the configuration information about the security drivers installed on a machine. It is located in the $SYBASE/SYBASE_REP/config directory in UNIX, or the %SYBASE%\ini directory in Windows.
This section provides the information you need to configure the security driver. Refer to the Open Client and Open Server Configuration Guide for more information about Sybase drivers.
The syntax for a security driver entry is:
provider=driver init-string
where
provider is the local name for the security mechanism, for example, “dce.” The mapping of the local name to a global object identifier is defined in objectid.dat.
The default local name for the DCE security mechanism is “dce.”
The default local name for the Kerberos security mechanism is “csfkrb5.”
If you use a local mechanism name other than the default, you must change the local name in the objectid.dat file.
driver is the name of the security driver, for example, libsdce.so.
init-string is the initialization string for the driver.
For the DCE driver, use the following syntax for init-string, where cell_name is the name of your DCE cell:
secbase=/.:/cell_name
For the Kerberos driver, use the following syntax for init-string, where domaine_name is the name of your Kerberos domaine:
secbase=@domaine_name
Use a text editor to customize libtcl.cfg for your site. Make sure that lines you do not want are preceded with the “;” character. Change one parameter at a time and reboot Replication Server to effect the changes you make.
An example of an entry for a DCE driver is:
[SECURITY] dce=libsdce.so secbase=/.:/cell_name
An example of an entry for a Kerberos driver is:
[SECURITY] csfkrb5=libsybskrb.so secbase=@ASE libgss=/krb5/lib/libgss.so
